Mortality and factors associated with acute exacerbation after non-cardiac surgery in patients with interstitial pneumonia: a retrospective study.

ABSTRACT:

Background

Acute exacerbation of interstitial pneumonia (AE-IP) is associated with high mortality rates. Although the risk factors for AE-IP have been extensively studied, given the small sample sizes, only a few risk factors have been established. This study aimed to investigate the postoperative mortality and factors associated with AE-IP.

Methods

This retrospective study included 482 patients with a preoperative diagnosis of IP who underwent noncardiac surgery between December 2012 and April 2020. AE-IP was diagnosed by a radiologist using computed tomography when worsening respiratory symptoms were observed within 1 month postoperatively. The Cox proportional hazards model was used to compare mortality rates. Candidate factors associated with AE-IP were identified throug
